I have a cheapy smoothie blender from Wal-Mart - I always "hide" things in my kids smoothies and they never know unless I tell them - carrots, spinach, avocado, etc. Other than the seeds from strawberries it completely purees everything, you cannot tell what's in them.
I like to make spaghetti sauce and "hide" things in it - eggplant, summer squash, peppers, carrots, celery, man, I've put so many veggies in spaghetti sauce, just use an immersion blender to make it smooth and they never know! Same with soups - I make potato veggie soup and blend it, nice & velvety smooth and full of "weird" veggies, and they just chow down.
